100A Audio Inline Circuit Breaker Reset Fuse Holder 12V-24V DC with Manual Reset and installation Screws for Car Audio, Stereo Switch and Solar Inverter System

used for a 55 lb. thrust trolling motor. worked fine

product was as advertised, glad to do business with them

Use mainly for an on off switch with a little hopefully protection

The switch body itself is sturdy. The breaker is very responsive and doubles as a kill switch for maintenance on the circuit it protects. However, the end caps are very brittle. It would be nice if they were designed to accept heat shrink on the outside diameter so that it would help seal the internals. Next time I will be getting marine-grade breakers. If you use this for anything where you don't have to worry about being exposed to the elements it should do fine. Anything outside though, go the extra mile and get marine-grade.

I use these for a reset-able amp limiter on kids power wheels after converting from 12v lead acid to 18v Ryobi lithium batteries. Hopefully it protects the batteries from dangerous current draws near dead battery levels. Haven’t had any issues yet (over 1 year)

I first installed the 100amp fuses in a automotive application in the winter. They seemed to work without issue during the winter months. I typically never put much more than 50amps through them. However, as soon as it got warm outside one of them tripped at about 20amps. The other one continued to work better as it was in a cooler setting. But eventually the second one started to trip with 35 amps after running the current through it for 5 minutes or so. After the breaker cools off I could reset it and run it for another 5 minutes. So this tells me that these breakers use some kind of a thermal switch to trip them. Additionally, its seems they get more sensitive over time. They have become unusable and untrustworthy. I would NOT recommend them.

These are the perfect size for my off grid solar setup. I put them in line with my solar panels and inverter, as well as inverter and batteries. Very simple for me to disconnect and safely work on my setup without live wires or a risk of sparks when connecting items.

Used this device to protect my solar panel installation and it also gave me any easy way to turn off the incoming from the panels by hitting the button and opening the input.

Worked like a charm, was probably 120 for a new part for the positive terminal fuse box thing on my sister extera and she was broke and stuck at a store parking lot for 2 days till i found a really temp fix to get it home and this solved her issue for cheap. Now if the breaker pops its just a flick of the switch to get the starter to turn over. Also secondsa as a night switch now ;) lol..

AAA+++

These breakers are advertised for car audio use, but I am using them with my small solar system. I bought the low current 30 amp circuit breakers. They installed easily, The switch part works well. I don't know if the circuit breaker works as I don't intend to deliberately overload the system. They handle my 12 gauge wire from the array (400 watts/40 volts) and the 8 gauge wire to the two 12 volt 100 AH gel cells just fine. The breakers have been installed and working for about 2 weeks at this point. Long term reliability is an unknown.

Well built replacement for my tired breakers that were on my boat when I bought it. Works great.

I purchased this breaker the other day for use in my vehicle to connect an air compressor. Air compressor draws 80amps and the breaker was 150. Every time I turned on the air compressor, it would trip the breaker. Purchase two of these and have the exact same problem. Stay away from these and buy a high-quality breaker.
